NOTE: After 29 years and 1000’s of math problems, Macalester Prof. Wayne Roberts will retire from his post as League founder and director. He started the League in 1980 with four teams. Today, 173 schools make up the League and over 3,000 students participate statewide. As he put it, “No one ever wrote to thank me for writing a calculus book, but many students and parents have called and written to thank me for starting Minnesota’s Math League.”
